Ok so here's a lil back ground on what's going on. I bought th bike back in April. I just started back riding around that time so I babied her til I was back comfortable after a month or so. I would do 135-150 with no issues. Fast forward to June I busted my oil pan and it sat up at an associates house for like a month. once that was fixed it wouldnt start,so the fuel pump had to be replaced but the guy reused my old filter cuz the new One they sent me didnt fit(too big).Finally after a month I had my bike back so I hop on the interstate and go full throttle and it jerks like its having a seizure and won't go over 85. It's been doing that for a few monts now...tried seafoam, replaced the plugs and stil the same issue. Please help!!!

Check your ignition system, usually jerking issues at WOT and acceleration is related to ignition and fuel related issues usually have symptoms of felling like power is coming on and off with WOT and acceleration.

Id suggest starting by replacing your spark plugs and check the resistance of your plug leads and work your way back from there.

The perceived jerking is most likely the fuel not being ignited every cycle of the ignition.
